is a very odd year. I thought this would be informative to those owners. I feel like I am really being second guessed here and hope this thread will be taken down. No wonder so many commercial vendors who do this work day in and day out have stopped posting.
The bracket on the torsion axles was changed for the 1969 models.
to the 1968
trailers, the axle mounting plate, the plate welded to the outside of the chassis, is indeed very short in height that extends below the actual frame.
Many years ago, I got together with Henschen and the engineers at Airstream, to work out a "fix", so that the newer mounting plates can easily be used.
The answer was to drill 3 1/2 inch holes in the axle mounting bracket and through the axle mounting plate, and install grade "8" 1/2 inch bolts. We have offered that hardware kit for several years and so far, it has answered the question.
The next seemingly new obstacle wasthe increase in size of the square tube. Generally speaking, the square cut out must be enlarged. It's increase in size has nothing to do with any "alignment" issues, just so the axle can be raised in place.
The alignment for the new installation, is to make sure that the rear hole in the axle mounting bracket lines up exactly vertical with the rear hole in the axle mounting plate.
Drill the 3 new holes, install the hardware, and that side is done. Repeat the same for the other side as well.
Installing a replacement torsion axle when the original was welded in place, requires a little measuring to make sure that both axle mounting bracket dimensions are exactly the same from the leading edge of the bracket, to the center of the jack post on the A frame.
Then, the replacement can be welded into place the same way as the original axle.
Dexter claims that the welding method will damage the rubber rods. We checked the temperature rise with an infra red gun, and found that indeed, the temperature of the area did rise.
Yes, the temperature did rise, to a whopping 16 degrees F.
The same rise in temperature happens when the shock brackets are installed.
Holy smokes, does that mean if the trailer is towed in the heat of the summer in Arizona, that the rubber rods go bad????
I don't think so, and I also disagree with the implied scare tactics.
